CORD-OLAMPING DEVICE.

Specification of Letters Patent.

Patented June 23, 1908.

Application filed October 10, 1907. Serial No. 396,708.

To all whom it may concern:

Be it known that 1, JAMES B. LEE, a citizen of the United States,residing at Knoxville, in the county of Knox and State of Tennessee,have invented a new and useful Improvement in Cord-Clamping Devices, ofwhich the following is a specification, reference being had to theaccompanying drawing.

My improvement relates particularly to devices for securing, withouttying, the ends of light or small cords and tapes, such as shoe stringsand similar cords or tapes used for lacing.

The improvement is applicable also for the securing of the ends of cordsused otherwise than for lacing through such eyelets or hooks as areordinarily applied to shoes, gaiters, leggings, and similar articles.

The object of the improvement is to produce such a device in a formadapted (1) to easy securing to leather or similar sheet-form material,and (2) to permit the ready drawing of the cord into a firm andeffective engagement and the ready Withdrawal of said cord from suchengagement.

In the accompanying drawings, Figure 1 is a plan of a clamping deviceembodying my improvement; Fig. 2 is a side elevation of the same device;Fig. 3 is a plan similar to Fig. 1 with an eyelet applied for securingthe device to a sheet of leather or cloth; Fig. 4 is a section on theline 41-4 of Fig. 3; Fig. 5 is a perspective view of an uncompressedeyelet such as is shown applied in Figs. 3 and 1; Fig. 6 is a section onthe line 6-6 of Fig. 1.

My clamping device is an elongated, onepiece flexible wire structure,one end of which is secured to the leather, cloth, or other sheetformmaterial, and the other end of which is ada ted to yieldingly clamp orpinch the cor at two places.

Referring to said drawings, 1 is an approximately horizontal tongueformed by folding the wire upon itselfin a horizontal plane, the closedor outer portion of the tongue being directed away from the end of thedevice which is secured to the leather or other material. At each sideof the tongue, 1, is a jaw, 2, resting in a plane slightly oblique tosaid tongue, so that the inner 'end of the tongue normally restsslightly above said jaws. The tongue and the jaws are joined by loops,3, standing in plane'swhich are approximately upright and parallel toeach other and said tongue and jaws.

From the inner end of each jaw, 2, the wire by means of an eyelet, 6,extending through the sheet, 7, of leather or similar material andhaving its lower flange binding against the lower face of the leatherand having its upper flange binding over said arms. Where said arms passaway from the eyelet to join the jaws, 2, the upper flange of the eyeletshould be cut away to form notches, 8, as shown in Figs. 3 and 5, saidnotches being of proper form to receive said arms.

For the securing of a cord, 9, the cord is drawn sidewise along theupper faces of the inner portions of the jaws, 2, and beneath the innerportion of the tongue, 1, (the adjacent curved portions of the loops, 3,serving to guide the cord downward) and toward the outer end of saidtongue and jaw. In this way, the cord is engaged at two places, namelybetween each side of the tongue and the adjacent jaw, 2, the tongueextending partially between said jaws, as above described, so that thecord is wrapped partially around the wire at each side of the tongue forthe making of greater frictional engagement (see Fig. 6). The tongue, 1,the loops, 3, 3, and the jaws, 2, 2, together make a suflicient lengthof wire to permit suflicient movement of the tongue even when the wireis strong enough to make a strong resistance to flexing.

As shown in the drawings, the tongue, 1, extends forward far enough toprevent the cord from passing over such end when the cord is, at anytime, drawn forward as far as the jaws, 2, extend.

For the releasing of the cord, it is forcibly drawn sidewise away fromthe outer end of the tongue and jaws until it is freed from the clampingor gripping.

I claim as my invention:

1. A one-piece wire clamping device of the nature described comprising atongue, a aw at each side of said tongue, loops joining said jaws andsaid tongue, and arms for securing said device to sheet-form material.

2. A one-piece wire clamping device of the nature described comprising atongue, a aw at each side of said tongue, loops oining sald jaws andsaid tongue, and curved, approximately semi-circular arms extending fromsaid jaws.

3. A one-piece wire clamping device of the nature described comprising atongue, a jaw at each side of said tongue, loops joining said jaws andsaid tongue, and arms for securing said device to sheet form material,said tongue extending beyond the outer ends of said jaws.

4. In a clamping device of the nature described, the combination with aone-piece wire structure comprising a tongue, a jaw at each side of saidtongue, loops joining said jaws and said tongue, and curved,approximately semi-circular arins extending from said jaws, of an eyeletengaging said arms.
